4 Claims, 3 Drawing Figures RUBBISH DISPOSAL INSTALLATION It has beenthe custom in garden apartment and other two and three story buildingsto install what is known as Class II incinerators which consist of avertical chimney having a grate and fire door at the bottom and doors oneach floor of the building so that rubbish may be disposed of by dumpingit down the chimney.

The rubbish to be disposed in such buildings consists of all forms ofhousehold waste and garbage much of which is not readily combustible,and some, such as cans and bottles are not combustible at all. It hasbeen necessary, therefore to supply heat by appropriate fuel burners toconsume as much as is practical of the refuse. The residuum must then beremoved from the combustion area and ash pit and placed in disposalcontainers from which it is transferred to trucks for dumpmg.

These Class II incinerators are not efficient nor economical of fuel,time or labor, and, under present conditions of increasing populationdensity requiring anti-pollution measures to be put into operation useof Class II incinerators will probably be prohibited in the near future.

One of the reasons in the past for use of such incinerators was thatthey are inexpensive to install and, while creating smoke etc., they didreduce the weight of refuse to be hauled away by trucks.

It is an object of the present invention to provide a means similar toClass II incinerators in so far as inexpensive installation costs areconcerned, either as original equipment or as a kit which a presentlyinstalled Class II incinerators may be converted to provide the sameconvenience to the tenants in the building while eliminating the airpollution, the use of fuel, and to reduce the labor required by thebuilding janitor by elimination of the need to shovel out ash pits anddump the grates as is required in the use of Class II incinerators.

Other and further objects and advantages will appear from the followingspecification taken with the accompanying drawings in which likereference characters refer to like parts in the several views and inwhich:

FIG. 1 is a front elevation of the device of the present inventioninstalled;

FIG. 2 is a section on line 22 of FIG. 1; and

FIG. 3 is a section on line 33 of FIG. 1.

The device may be installed in an extant Class II incinerator structureby inserting a lintel above the present fire door that gives accessabove the grate and removing the wall and doors below this new lintel.The new lintel is shown in FIG. 2 at 10. The mason then will inserttrack elements 12, one on each side of the flue 14, and one across therear wall.

This track element is preferably of box construction, rectangular asseen in section, the box portion preferably having overall dimensionssuch that it fits into masonry as standard sized fire brick would, butany appropriate size may be selected. The flange 16, forming the actualtrack may, of course be of any appropriate dimension but a projection of1%inches is considered to be desireable.

A funnel like chute 18 is formed having an outwardly extending flange 20at its uppermost extremity. This funnel like chute is rectangular at thetop and of such a size that the flange 20 overlies the track 16 alongthe sides, and across the back of flue 14. The front of the chute 18extends across under the front surface of the flue 14. This would leavean opening between the top of the chute and the lintel 10 which,however, maybe closed by a plate 22 held in position by a clip 24. Thebottom edge of plate 22 is spaced slightly above the plane of tracks 16to permit easy passage of flanges 20 between the track 16 and plate 22.Preferably a stop 26 is fixed on the flange 20 across the front of chute18 and contacts plate 22. Since heat is not used in the device, aresilient sealing element similar to Weatherstripping may be used at 26if desired. To hold chute 18 in position a headed pin, or bolt 28 isdropped into a hole drilled in the track 16. The flange track 16 may beclosed adjacent the plane of the lower surface of lintel 10 which willeliminate the need for plate 22.

The lower end of chute 18 is shown as being cylindrical and of adiameter substantially that of a rubbish or waste handling container 30.Chute 18 could, of course, be rectangular at its lower end ifrectangular rubbish containers 30 are to be used such as might beconvenient for use in connection with refuse baling machinery to whichthe rubbish collected in container 30 is to be delivered.

Surrounding the lower end of chute 18, whether cylindrical orrectangular, is a vertically movable telescoping element 32 that isslightly larger than chute 18 so it can be raised and lowered withrespect to chute 18. To the lower end of telescoping element 32 aclosure flange 34 is fixed which seats on but does not grip the top edgeof refuse container 30.

To raise and lower closure 34 two levers 36 are pivoted, at each side,to a frame 37, by pins 38. The telescoping element 32 is provided ateach side with a pin 40 that engages an aperture 41 in lever 36. A bar42 connects the ends of levers 36 so that the two levers are actuatedsimultaneously by depression of handle 42 to raise closure 34 fromcontainer 30 so that the container 30 may be removed, and an emptycontainer be put in position and closure 34 brought down to close theempty container by release of bar 42.

In operation of a garden type apartment having, say ten refusecollecting devices as described above the janitor needs only to replacefilled, or partly filled refuse containers 30 periodically by pressingdown on bar 42, pulling the container 30 out from under chute l8 andpushing a replacement container into position. The refuse in the filledcontainer may be collected in the usual way by trucks, or may be baledbefore it is picked up by truck for disposal at some distant point.

There is, of course, no smoke, ashes, fumes, or vapors developed in thisrefuse disposal system, the closures 34 fits snugly preventing spillageof refuse and preventing access to the refuse .in container 30 byrodents. If, however, a glowing cigarette or the like shouldaccidentally be dropped down flue 14, the tightness of the device willprevent more than a minimum of air to be drawn into the flue so anyblaze that might break out will be smothered, but even in case a moresubstantial flame were developed, the fire will be contained in flue 14and can be readily extinguished.
